Here is an interesting article by a Registered Dietician(By Sheila Tucker, MA, RD, LDN
Administrative Dietitian, B.C. Dining) written for Boston College Dining.
Tucker recommends 1.4-1.8 grams per kilogram body weight when building new muscle vs. 0.8 grams per kilogram for sedentary people.
You weight converted to kilograms is about 77.5 so your protein needs shouldn’t exceed 140 grams or so until you reach a higher weight. Although I am impressed you can eat that much protein, you could reduce your protein intake by a whopping 135 grams and take a lot of stress off your kidneys. Adding an equal amount of carbs would keep the calories the same and probably speed your metabolism.
